Too many data missing on custom post types

Hello,
thanks for programming this. It looks fine with normal posts.
And thanks to your hint I was able to use it with custom post type (Woocommerce products) as well.
But there are too many custom information/data missing on the amp version:
– prices
– stocks
– product gallery
How can we add this information?
Right now my webpage is alredy mobile friendly and optimized with structured data. So there is not need for this.
